Caution!

You are handling dangerous

electrical current!

Disconnect the supply voltage before making any wiring

modifications.

Ensure that the system cannot be switched on accidentally.

Ensure that the device and its surroundings are potential free.

Please refer to the specific installation and mounting instructions.

Qualified personal only should handle the device.

The device has to be mounted in such a way that no unintentional

operation may occur.

All control and supply voltage wiring must be routed so that no

inductive or capacitive interference or any other severe electrical

noise disturbance may interfere with the device.

Supply voltage variation must not exceed the specifications in the

technical details. If so, proper performance of the device cannot be

guaranteed.

Emergency installations according to EN60204/IEC204 (VDE0113)

must remain active in all modes of the automated installation.

Activation of the emergency installation must not cause an

uncontrolled or undefined start cycle.

The software engineer has to make sure, that no failure functions

of the automated installation may occur when line faults or core

faults arise.

Notwithstanding the above, local regulations must be observed in

all installations.

Safety-related advice

Danger to life through electrical current!

Only skilled personal trained in electro-engineering should perform

the described steps in the following chapters. Please observe the

country specific rules and standards for the mini module

installation. Do not perform any electrical work while the device is

connected to power!

Please pay attention to the following rules:

 Activate the automated installation

 Disable any automatic restart system.

 Electrically isolate the installation

 Cover any non-isolated areas

Introduction

Since the data from SLS-500-MBUS-MODBUS Converters can be

read from any Modbus-Master (automated control, visualisation

system etc...) a very broad range of applications becomes

possible. For instance data from a heat meter can be easily

represented on a mimic display. Each MBUSMODBUS Converter

module can read the data from up to 8 Meter bus unit loads ( 1 unit

load corresponds to 1,5 mA current consumption of one

participant). Thus maximal 8 devices each one unit load can be

connected to one MBUS-MODBUS Converter. The current

consumption of a device can be seen from the respective data

sheet.

The data to be read are freely configurable and are automatically

actualised in selectable periods of time.

Description of the

functions

The SLS-500-MBUS-MODBUS converter automatically reads

preconfigured values from MBUS meters and makes them

available in Modbus holding registers. Up to 100 values can be

read via Modbus.

On application of the supply voltage the converter verifies if a valid

configuration is available or not. If so, the converter starts to

initialise all MBUS meters. If no answer is received from an MBUS

device within three consecutively initialising attempts it is skipped

and the next meter is initialised. The initialising procedure is

repeated every 5 query cycles. After a pause of 5 seconds the first

query cycle begins.

The values of all initialised devices are read and depending on the

configuration written into the respective Modbus registers. From

now on the selectable pause time between two query cycles is

activated.

If no answer is received from an initialised MBUS device within

three consecutively reading attempts, this device is reinitialised

within the following working cycle. After three failed initialising

attempts, another attempt follows every 5 cycles. After successful

initialisation the data are read in the following cycle.

Most of the MBUS slaves actualise their values only after a query

has been performed. As the converter allows the definition of

pauses between queries to up to 18 hours, the following

mechanism avoids that ‘old’ values are read:

If pauses between queries are longer that 30 seconds, the

converter requests all slaves 30 seconds before the real query to

actualise their values.
